WebSocket frames are now aggregated through a Netty decoder so that
we always receive fully assembled messages by default capped at 64K.
Issue: SPR-14527
Rename classes not specific to Tomcat:
TomcatWebSocketSession -> StandardWebSocketSession
TomcatWebSocketHandlerAdapter -> StandardWebSocketHandlerAdapter
WebSocketSessionSupport is renamed to AbstractWebSocketSession since it
actually is a WebSocketSession and pre-implements a number of methods.
ServerEndpointRegistration is now package private (mainly for use in
upgrade strategies) and renamed to DefaultServerEndpointConfig.
Switch from returning Mono<WebSocketSession> to take a WebSocketHandler
and return Mono<Void> for the entire session handling.
The WebSocketHandler callback delimits the stard and end of protocol
handling and forces the handler to operate within the scope of the
Reactor operators.
Give the full duplex nature of WebSockets, the symmetry between client
and server (each now using WebSocketHandler) also seems appropriate.
Issue: SPR-14527
The WebSocketHander adapters are now neutral for client vs server-side
use with the adapters for RxNetty and Reactor Netty (server-side only)
completely removed.
A new HandshakeInfo carries information about the handshake including
URI, headers, and principal from the upgrade strategy, to the adapter,
and then to the session.
WebSocketSession exposes the HandshakeInfo as well reducing its overall
number of methods.
Move WebSocketMessage factory methods to the WebSocketSession which
has the bufferFactory() needed to create message payloads.
WebSocketMessage is left with one public constructor.
WebSocketMessage exposes convenience retain/releasePayload methods.
Expose bufferFactory() at the WebSocketSession level for creating
payloads like ReactiveHttpOutputMessage does.
Promote getId(), getUri(), and bufferFactory() to the base class
WebSocketSessionSupport.
Apply the new HttpHeaders#getAcceptLanguageAsLocale() in places where
it was hardcoded or defaulting.
Apply ServerHttpResponse.encodeUrl in RequestContext.
Issue: SPR-15024
An update on the last commit switching from:
List<Locale> getAcceptLanguageAsLocales() to
Locale getAcceptLanguageAsLocale()
This best supports the scenario for the most preferred Locale.
If there is a need to look at the prioritized list of languages it's
best to use Locale.filter with the LocaleRange's.
This is explained in the Javadoc for getAcceptLanguage().
Issue: SPR-15024
The use of Locale.LanguageRange for the Accept-Language header makes
sense as it gives the most flexibility for a client to set a weighted
list and for a server to do filtering via Locale#filter.
This commit adds an additional convenience method that turns
the LangugeRange list to a list of Locale's also filtering out a
wildcard (i.e. "*"). A List<Locale> is the most basic way to access
prefered languages and needed when filtering is not required.
